Mesenteric cystic lymphangioma in an adult: An unusual case report.

Introduction: Cystic lymphangioma is a benign malformation tumor of the lymphatic system. Its location is variable, and mesenteric localization remains extremely rare.

Case Presentation: We describe a rare case of cystic lymphangioma of the mesentery in a 26 years old woman.

Chromophobe Renal cell carcinoma revealed by stercoral peritonitis: case report.

Background: Sarcomatoid transformation in chromophobe renal cell carcinoma is extremely rare.Gastrointestinal symptoms in renal cell carcinoma are rare and are often secondary to the tumor local growth. While these symptoms are essentially represented by gastrointestinal bleeding, symptoms related to colonic perforation are extremely rare.

Neurofibromatosis type 1 associated multiple and cystic gastrointestinal tumors: 02 case reports.

Introduction: GIST's are the most common mesenchymal tumor of the gastrointestinal tract, clinically and radiologically heterogeneous, only a histological study can confirm the diagnosis. The link between NF1 and GISTs have been established but not fully elucidated.

Case Presentation: we report 02 cases of NF1 associated GIST, a 60 years old woman with multiples GISTs in the duodenum, proximal jejunum and in the colon presenting an iron deficiency anemia due to chronic bleeding, operated with R0 resection and a low risk of recurrences and a 41 year old male patient with acute abdominal pain with a giant abdominal mass mimicking a hydatid cyst with no relevant medical history, diagnosed at the same time for typical clinical NF1, CT scan showed the cystic mass but did not confirmed its origin, a complete resection of the mass with no capsule fraction was tricky but successful and the histopathology found a high risk of recurrences.
